Multi-Stage Flash (MSF) desalination is the innovative technology for the production of very clean, drinkable water using vacuum distillation. The application varies from individual households to industrial enterprises. The technology is delivered as the distillation unit with brine recirculation. Model series of the unit modular system ranging from 1 to 1500m3 of freshwater/day. The capacity can be increased, thanks to the modularity. This flexibility is especially convenient for use on ships and in other confined spaces. The simplicity of the technology, very easy operation, and maintenance enable the maximal operating time of 350 days/year. MSF Technology represents a viable and more cost-efficient alternative to traditionally used Reverse Osmosis.
MSF is the innovative technology for production of very clean, drinkable water using vacuum distillation, which:
MSF is an innovative technology for the production of very clean water through vacuum distillation. The quality of the drinking water is much higher than with other traditional desalination technologies like Reverse Osmosis.
If the waste heat is used to run our desalination unit, running costs are nearly free of charge. That’s why water can be used for irrigation in moisture lacking areas. This enables intensified farming throughout the sustainable development.
Fish after being caught need to be washed in fresh water so that they can be frozen. From the waste heat of the vessel’s engine with the help of our unit, fresh water can be produced directly on the ship. Water can be used for drinking on the vessels as well as on any kind of ship.
It is our intention to expand and develop additional methods of application of the unique MSF technology where there is a shortage of clean water.
The goal is to make quality, cheap water available to everyone who suffers from a water shortage, enable soil irrigation in areas that are now being lost to advancing deserts, and/or where the growing of crops is impossible due to lack of moisture. In addition, we strive to provide all users of technical equipment and means of transport the opportunity to utilize the waste heat in producing water. Such means of transport include ships, from giant tankers to small yachts, where the need for pure water is imperative.
World seas and oceans cover 71% of the Earth’s surface. By making use of wasted heat and energy that contributes to global warming, we can easily produce very cheap, affordable drinking water from the sea.
Any renewable source of energy like solar, wind, or hydrothermal, can be also used for the desalination process and production of safe drinking and irrigation water.
While using existing sources of waste heat the MSF technology can produce clean drinking or irrigation water for close to zero running cost.
MSF technology is very simple for operation and maintenance thus it is suitable also for the remote locations with limited skilled labor force available.
MSF is a modern environmentally friendly technology that does not contribute to the creation of greenhouse gases and global warming.
According to medical statistics, contaminated water is responsible for up to 80% of diseases among populations in some areas. It is important to know that MSF technology removes not only salt but also other mineral and microbial contamination from the water. This is of major importance in areas where water contamination causes serious health problems.
Reduced pressure inside the device leads to a marked decrease in the water’s boiling point. This equals lower energy consumption and lower cost of drinkable and usable water produced.
Our modern desalination technology, based on vacuum distillation, allows for the production of high-quality drinking water. which can be used for the irrigation of farmlands without soil degradation.
Our technological design enables the use of waste heat that is produced as a by-product in many production processes. This technology does not contribute to global warming.
With our modern MSF technology, we are able to produce high-quality drinking water from seawater with almost zero operating costs; we do this while utilizing waste heat.
The MSF technology is most commonly used to produce drinking water from seawater. This is the case for individual households, small (resorts, hotels, restaurants, bakeries, etc.) and mid-size businesses and enterprises as well as public facilities like schools, clinics and hospitals in coastal areas. The MSF technology works perfectly on ships as there is always a source of waste heat (engines) and other industrial plants and facilities. MSF could easily be used for production of irrigation water to prevent agricultural soil salinization.
It is important to explain that the MSF technology removes not only salt, but also other mineral and microbial contamination from the water. This is of major importance in areas where water contamination causes serious health problems. According to medical statistics, for example, contaminated water is responsible for up to 80% of diseases among populations in some areas.
It is also possible to use the MSF technology for the finest purification of fresh water that has already been produced by the Reverse Osmosis (RO) technology. Since RO cannot purify water to level lower than approx. 300 ppms, it is recommended to use the MSF technology as an additional step in the treatment for water intended for drinking.
MSF makes it possible to produce baby-grade water and purify it to a measurable value of less than 1 ppm (part per million); that is, one millionth of dissolved matter. In contrast, the conventional method of reverse osmosis (RO) has difficulty keeping the output water value at 300 ppm (that is only with new filters and well-adjusted equipment). That is why you can often smell seawater after flushing the toilet or in the washbasin in seaside resorts that use the RO technology.
As with any technology that purifies water thoroughly, it is advisable to re-mineralise the water for drinking purposes. This is done using a capsule of dolomitic limestone that is part of the desalination unit. Moreover, MSF can be regulated to any reduced level of preservation of minerals from the original (input) water. This is another difference from conventional technologies like (RO). Another option is to add fertilizers and trace elements to purified (output) water intended for agricultural irrigation.
The cost of water is influenced by several factors; notably, the possibility of using any type of waste heat. For example, the MSF equipment can be connected to diesel generators, transformer plants, engine rooms, motors, exhaust pipelines and so on. The device can be connected to standard heat sources too.
All of that affects the resulting price of the drinking water. That is why it is necessary to determine the price based on the concrete conditions at the point of application.
Nevertheless, it can be said that the water production is so cheap that it can be used not only for drinking and cooking but also for irrigation. The conventional RO technology cannot be used for irrigation due to both its higher cost and the progressive soil degradation due to high salinity.
The MSF is designed as a modular system with a standard capacity in the range from 1 to 1500 m3 of pure water a day. The capacity can be increased at will, thanks to the modularity. The modular system also allows for maximum equipment adjustability to a particular area or environment. The modules can be arranged and shaped in any way. This flexibility is particularly useful when employing MSF (or the EME application) onboard ships and in other confined spaces.

MSF technology can use – as its only source of energy – something called ˈwaste heatˈ. It is heat that is generated as a by-product when producing electric power, burning garbage or transforming high voltage current to low voltage current. The MSF technological design enables use of waste heat from all sorts of technological equipment: diesel generators, transformer stations, engine rooms, engines, heat exchangers, incinerators, etc.; allowing for the cheapest water production possible, while not producing additional emissions.
While using the heat that would otherwise be wasted, you can decrease the operating cost of the technology to almost ZERO. Thus, it is possible to produce high quality drinking water at an extremely low cost.
The device requires next to zero maintenance; the only scheduled downtime is for simple cleaning. The total time of MSF operations, excluding scheduled downtime, is 330 days a year. The technology has been tried and tested in real environments.
The MSF equipment is fundamentally simplified so that it is applicable without risk in developing countries, where skilled operators are not likely to be available.
The technology can be equipped with remote monitoring (a GSM gateway with periodic dispatch of operating data, i.e. information on operating history and failure reports).
No, it does not. We recommend roofing, fencing or otherwise securing the MSF equipment against vandalism or destruction.
Unlike with RO, there is no need for buildings or complex filtering equipment for pre-treatment. There is also no demand for large amounts of electricity for high-pressure pumps, frequently powered from diesel generator plants. This eliminates the need for building such facilities with adjacent oil and fuel handling facilities, which require numerous skilled operators. Finally, there is no need to replace the osmotic membranes every 5 years; membrane replacement accounts for 30-40% of the total price for the RO technology! MSF is based on vacuum, that is why doesn’t have any membrane.
As a team of environmentalists, we hope one day to see advancing inhospitable deserts turn back into green areas full of wildlife and lush vegetation.
Our mission is to enable access to safe drinking water for everyone who suffers from a shortage thereof. We know that the journey ahead is very long. Still, we have a vision for making this happen and believe this goal can ultimately be achieved.
